2 Claims. (01. 221-21) This invention relates to nozzles for metal,fibre tion which are now deemed preferable, but it is and the likecontainers, and more particularly to pouring nozzles therefor having aspout extending from'the container when in use and retractable toaposition within the nozzle opening and container during shipment, orwhile not in use.

An object of the present invention is to provide a container for liquidsand othermaterials, with a, nozzle having a dispensing spout which maybe withdrawn from a nozzle opening into pouring position or retracted toa position within the nozzle opening to permit sealing and closing theopening by means of a conventional closure cap.

Another object of the invention is to provide a retaining ring for thepouring spout and through which ring the spout is freely slidable but isprevented from removal therefrom by suitable flanges at the oppositeends of the spout, the ring being insertable within the nozzle openingand frictionally or otherwise retained therein.

With the above and other objects in view the invention includes thefeatures of construction and operation set forth in the followingspecification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of thisspecification, I have shown the invention embodied in a metal containerof medium size particularly for If uids but it will be understood thatthe invention can be otherwise embodied and that the drawing is n0 to beconstrued as defining or limiting the scope of the invention, the claimsappended to this specification being relied upon for that purpose.

In the drawing-- 4 Fig. 1 is an elevation partly in section of acomplete nozzle showing the pouring spout in its ex tended position infull lines and in its retracted position in broken lines;

Fig. 2 is an enlarged cross sectional view of a portion of the nozzleshowing the pouring spout retracted and a closure cap in position toclose the nozzle opening;

to be understood that changes and modifications may be made within thescope of the appended claims without departing from the spirit of theinvention.

Briefly, and in its preferred aspect, the inven tion may include thefollowing principal parts: First, a nozzle having an openingtherethrough and suitably attached by crimping, soldering or otherwiseto a surface of a container through which an'opening has been provided;second, a retaining ring or disk having a periphery adapted to fitfirmly within a portion of the nozzle opening; third, a pouring spoutslidable within an aperture provided in the retaining ring; fourth,flanges at the opposite ends of the pouring spout to prevent removal ofthe-retaining ring therefrom; and fifth, a flexible member in the formof a washer housed within the retaining ring and firmly contacting theoutside surface of the pouring spout."

Referring more in detail to the figures of the drawing there'is shown atII) a portion of a container in the form of a metal can or drum adapt-.

ed for liquids or any other material that may be poured. Within the topwall of this container is a nozzle II preferably of standard form whichmay be crimped or otherwise secured in this top wall, adjacent sidewalls of the container in the usual manner. This nozzle II has avertically extending opening, the upper portion of which is slightlyenlarged to form an annular ledge l2. Also the nozzle I I may beprovided on its outside surface with sections having spaced projectionsover which the threaded portion of a closure cap I3 may be mounted andscrewed into contact with the upper edge of the nozzle.

Insertable within the nozzle opening is a re- I taining ring I4 whichpreferably may be made of Fig. 3 is a plan view of a retaining ring fora pouring spout having a non-circular section;

Fig. 4 is an elevation of a non-circular pouring spout showing a nozzlehaving a-reta-ining ring therein;

Figs. 5, 6 and '7 are sections of non-circular.

sheet metal doubled upon itself as seen in Figs. 1 and 2. The outerperiphery of this ring I4 closely engages the inner surface of thenozzle I I at its larger diameter and rests upon the narrow peripheralledge I2. Preferably this ring I4 may be pressed firmly into theposition shown in Figs. 1 and 2 so that it may be frictionally retainedtherein. When secured in this manner the ring I! may be removed from thenozzle if desired and reinserted without difficulty and withoutrequiring any special holding means.

The ring I4 as shown in Figs. 1 and 2 is centrally apertured and at theperiphery of this opening is provided a felt or'other form of flexiblewasher I5 housed within the metal portion of the ring. Slidable throughthe aperture withdisk [9 may be placed the retractable pouring spout it.This spout it is curved'at one end upon a convenient radius so thatwhenwithdrawn from the container ill its .free endmay extend beyond the sidewalls 01 the container to facilitate. pouring.

The spout is at its outer end Imay be straight or substantially straightand as longas desired. In retracted position the spout assumes theposition shown in broken lines in Fig. 1 andthe straightportion of thespout extends vertically downward from the nozzle H and the curved innerend of the spout may extend substantially to the side wall of thecontainer it.

At the opposite ends of the spout l6 are flanges I! whichmay be formedby rolling the end of the metal forming the spent it or by any otherpreferred means. By means of these flanges H, the spout It may not beseparated from the retainer ring H but may slide freely through the ringand the felt washer 15. In its extended position one of the end flangesl'l bears against the surfaceof the retainer ring M, which. contact,aided by the felt washer stantially closed joint and prevents liquidfrom running down the outside of the spout during pouring. Whenretracted within the'container ID the opposite end flange l1 bearsagainst the upper surface of the ring I 4 and lies below the upper edgeof the nozzle II. In this position of the spout ample room exists forthe cap I3 to be screwed down upon the nozzle and the spout is preventedfrom rattling.

In Figs. 3 and 4 is shown a non-circular form of pouring nozzle I 8 thesection of which is triangular to provide a narrow pouring lip. Thisform of spout I 8 may be bent along its length as desired or similarlyto the form shown in Figs. 1 and 2. The retaining ring l9 for this noncircular form of spout I8 may be formed conveniently as shown in Fig. 3by suitable bending operations to form folded portions, the periphery ofwhich is circular. Between the folds of this a felt washer 2o aperturedto closely fit the sides of the spout l8. Preferably and as shown inFig. 3 the disk I9 is apertured to permit the spout it freely to slidefrom end to end. Flanges 2| at opposite ends may be provided similar toflanges ii to prevent the spout l8 from being withdrawn completelythrough the disk l9.

l5, forms a sub- Alternate forms of spouts are shown in Figs. 5, 6, and7, and it will be understood that retainer rings apertured to correspondto these forms will be employed and having a periphery fitting tightlywithin the nozzle opening.

In Fig. 8 there is shown a modified form of nozzle 2! in which theheight above the annular ledge 22 is increased to permit theintroduction of a tamper proof disk or plug 23. The disk 23 may beforced frictionally into the position shown in this figure after theretaining ring 24 and spout 25 have been inserted. Also the inner wallof the nozzle 2i just above the retainer ring 24 may be provided withlugs 26, one only being shown in the figure, to permanently andpositively retain the ring 24 in position. A closure cap 21 similar tothat shown in Fig. 2 is also provided.

I claim as my invention:

1. A retractable pouring spout for metal containers comprising a tubularnozzle secured to a wall of said container, an annular ledge formedwithin the inner wall of said nozzle, a metal retainer ring removablysecured within said opening and bearing against said ledge, said ringhaving a flexible washer housed therein between upper and lower surfacesof said ring, and a tubular pouring spout flanged at its opposite endsand slidably disposed within said retainer ring while in engagement withthe inner surface of said washer, whereby said spout may be maintainedagainst removal from said ring and slidable thereon throughout itsentire length.

2. A retractable pouring spout for metal containers comprising a nozzlehaving an .opening therein secured to a wall of said container, anannular ledge formed within the inner wall of said nozzle at anintermediate point thereof, a retainer ring secured within said nozzleand bearing against said ledge so that the ring will be disposed belowthe open end of said nozzle. said ring having an aperture therethrough,a tubular spout having flanges at its opposite ends slidably fittingsaid aperture between said flanges, and an annulus of flexible materialhoused within said ring and contacting said spout, whereby said ring andspout may be removed from said nozzle and said spout is prevented frombeing removed from said ring.
